[0027] The present disclosure first provides a photovoltaic panel assembly fixing slide, such as Figure 1-Figure 4 As shown, it includes: a base plate 12, a lifting device and a photovoltaic panel assembly structure; a lifting device connecting rod 4 is arranged at the lower part of the photovoltaic panel assembly structure, and a lifting device corresponding to the position of the lifting device connecting rod 4 is arranged on the base plate 12, and the lifting device connecting rod and the lifting device are semicircularly meshed; a positioning device is also arranged on the base plate 12; each lifting device can be lifted and lowered independently, and is used to change the angle of the photovoltaic panel assembly according to the position information obtained by the positioning device.

[0028] The photovoltaic panel assembly structure includes a first photovoltaic panel 1 and a second photovoltaic panel. The first photovoltaic panel 1 is the top photovoltaic panel, and the number is one. The number of the second photovoltaic panel can be one or more. The second photovoltaic panel is telescopically arranged at the bottom of the first photovoltaic panel and is slidably connected to the first photovoltaic panel, so as to realize the stacking of multiple photovoltaic panels. When the corresponding working conditions are met, it can be slid and unfolded from the bottom of the first photovoltaic panel, thereby expanding the light receiving area of ​​the photovoltaic panel and increasing the power generation. The first photovoltaic panel is connected to the lifting device on the bottom plate through the lifting device connecting rod, and the lifting device connecting rod 4 is fixedly arranged at the corners of the first photovoltaic panel. In this embodiment, the shape of the first photovoltaic panel is rectangular, and the first photovoltaic panel fixing frame 2 is arranged around the outside, and a lifting device connecting rod 4 is fixedly arranged at the four corners of the first photovoltaic panel fixing frame 2. The shape of the second photovoltaic panel is the same as that of the first photovoltaic panel, and the second photovoltaic panel fixing frame is also provided on the outside. In this embodiment, two second photovoltaic panels are taken as an example to illustrate the structure of the photovoltaic power generation device. For the convenience of description, the two second photovoltaic panels are named as the second photovoltaic panel A and the second photovoltaic panel B, and the second photovoltaic panel A is located above the second photovoltaic panel B. A second photovoltaic panel fixing frame A8 is disposed around the outer side of the second photovoltaic panel A7, and a second photovoltaic panel fixing frame B15 is disposed around the outer side of the second photovoltaic panel B17.

[0029] The second photovoltaic panel realizes relative movement with the first photovoltaic panel by means of a telescopic motor and a gear rack transmission. The photovoltaic panel telescopic motor assembly is fixedly arranged at the lower part of the first photovoltaic panel fixing frame. A rack track is fixedly arranged at the upper part of the second photovoltaic panel. The output end of the photovoltaic panel telescopic motor assembly has a gear structure for meshing with the rack track to realize transmission.

[0030] Specifically, a photovoltaic panel telescopic motor assembly A3 is fixedly installed at the lower part of the first side (a side in the width direction) of the first photovoltaic panel fixing frame, and a rack rail A6 is installed at the upper part of the second photovoltaic panel A7 and the second photovoltaic panel fixing frame A8, and the rack rail A extends along the length direction of the second photovoltaic panel A; the output end of the photovoltaic panel telescopic motor assembly A3 is meshed with the rack rail A, and when the motor of the photovoltaic panel telescopic motor assembly A is activated, the gear at the output end is driven to rotate, driving the rack rail A to move and then driving the second photovoltaic panel A and the first photovoltaic panel to slide relative to each other.

[0031] The first photovoltaic panel assembly fixing groove 5 and the second photovoltaic panel assembly fixing groove 19 are also fixedly provided on the lower part of the two side edges along the length direction of the first photovoltaic panel fixing frame, and the two sides of the second photovoltaic panel A are slidably matched with the first photovoltaic panel assembly fixing groove 5 and the second photovoltaic panel assembly fixing groove 19 respectively, and sliding is achieved under the limiting action of the first photovoltaic panel assembly fixing groove and the second photovoltaic panel assembly fixing groove.

[0032] A photovoltaic panel telescopic motor assembly B18 is fixedly installed at the lower part of the second side (the other side in the width direction) of the first photovoltaic panel fixing frame, and a rack track B16 is installed at the upper part of the second photovoltaic panel B17 and the second photovoltaic panel fixing frame B15, and the rack track B extends along the length direction of the second photovoltaic panel B; the output end of the photovoltaic panel telescopic motor assembly B18 is meshed with the rack track B, and when the motor of the photovoltaic panel telescopic motor assembly B is activated, the gear at the output end is driven to rotate, driving the rack track B to move and then driving the second photovoltaic panel B and the first photovoltaic panel to slide relative to each other.

[0033] The two sides of the second photovoltaic panel B also slide in cooperation with the first photovoltaic panel assembly fixed slide groove 5 and the second photovoltaic panel assembly fixed slide groove 19 respectively, and slide under the limiting action of the first photovoltaic panel assembly fixed slide groove and the second photovoltaic panel assembly fixed slide groove.

[0034] The lifting device connecting rod 4 cooperates with the lifting device in a semicircular meshing manner, for example, the connection can be achieved by using a ball head and a ball socket to meet the adjustment requirements in any direction. The lifting device includes a lifting device lower structure 9 and a lifting motor 10. The lifting device lower structure includes a ball socket and a connecting rod connected to the ball socket. The output end of the lifting motor is connected to the end of the connecting rod away from the ball socket, which is used to change the lifting state of the connecting rod. The lower part of the lifting device connecting rod is a ball head, which is connected to the ball socket.

[0035] A positioning device and a controller 13 are provided on the base plate 12, wherein the positioning device is used to obtain the position information of the photovoltaic power generation device, and the controller is used to control the lifting and lowering of the lifting device according to the obtained position information, thereby changing the angle between the photovoltaic panel assembly structure and the horizontal plane, adjusting the orientation of the photovoltaic panel, better receiving solar radiation, increasing the area directly exposed to sunlight, and improving the power generation efficiency.

[0036] Specifically, the positioning device includes a GPS locator 11 and a gyroscope 14, which are used to obtain the device's position information and location information, respectively, and send the obtained information to the controller. The controller is connected to the positioning device, receives the information sent by the positioning device, determines the location information of the device, and matches the pre-stored position angle correspondence according to the location information to obtain the optimal direct angle that satisfies the photovoltaic panel to receive direct sunlight at the current position and the current moment. The controller is also connected to the lifting motors of each lifting device, and adjusts the lifting height of each lifting device by controlling the action of each lifting motor, thereby realizing the angle adjustment of the photovoltaic panel assembly.

[0037] The disclosed embodiment further provides a vehicle, the vehicle comprising a photovoltaic power generation device provided above. The photovoltaic power generation device is fixedly arranged on the top of the vehicle, and the photovoltaic panel assembly structure of the photovoltaic power generation device is electrically connected to the vehicle, so as to realize power supply to low-voltage electrical appliances in the vehicle, or further charge the power battery after the voltage is increased by a boost device to replenish the power battery with electric energy.

[0038] The vehicle can further design control buttons connected to the controller of the photovoltaic power generation device. The control buttons can be physical mechanical buttons, or integrated into the vehicle's central control screen and implemented as virtual buttons. Since the extension and retraction state of the second photovoltaic panel can be controlled and the number is one or more, the buttons can be designed according to the number of second photovoltaic panels, and the second photovoltaic panels can be numbered. Assuming that the buttons are physical buttons that can be pressed and lifted, and the number of second photovoltaic panels is n, n expansion photovoltaic panel buttons can be designed, corresponding to each second photovoltaic panel. For the Nth second photovoltaic panel, it is numbered N. After pressing "Expand Photovoltaic Panel N", the Nth second photovoltaic panel is expanded to increase the light receiving area. After lifting "Expand Photovoltaic Panel N", the Nth second photovoltaic panel is retracted. An "Expand Photovoltaic ALL" button can also be designed to control the expansion and retraction of all second photovoltaic panels at the same time. In addition, a mode switching button can be set to switch between "extended mode" and "normal mode". In "extended mode", manual adjustment of each second photovoltaic panel can be achieved through the button control method as described above. In "normal mode", the device can automatically adjust the second photovoltaic panel according to the vehicle state (stationary or moving), weather conditions, and location. Similarly, the lifting state of the photovoltaic panel assembly structure (i.e., the angle of the photovoltaic panel) can also be adjusted manually or automatically.

[0039] In the disclosed embodiment, multiple photovoltaic panels (no less than 2 panels) are stacked up and down through a device, and the lifting device, bottom plate and other structures are integrated into a photovoltaic power generation device assembly, and then the assembly is installed on other carriers, which can be cars or ships. The device has two usage modes: normal mode and expansion mode. In normal mode, when the carrier is in a high-speed driving state, the second photovoltaic panel is in a retracted state, and only the first photovoltaic panel fixed on the top layer can receive sunlight. The lifting device and the telescopic device are in a closed state, and the entire device is built into the carrier in a retracted state, which effectively reduces the wind resistance of the carrier at high speed and improves the stability of the carrier and the photovoltaic device; when the carrier is stationary, the lifting device can adjust the angle of the photovoltaic panel according to the position of the carrier, thereby increasing the area of ​​the photovoltaic panel directly exposed to the sun, and at the same time, the second photovoltaic panel is unfolded and in an expanded state to increase the light-receiving area.

[0040] In expansion mode, when the carrier is in a low speed or stationary state, the expansion mode can be manually turned on. The GPS locator and gyroscope send the azimuth information and location information to the controller respectively. The controller realizes the lifting height of the lower mechanism of each lifting device by calculating and controlling the operation of the lifting motor, so as to achieve the best direct angle for the photovoltaic panel to receive sunlight. The user can control the expansion area of ​​the photovoltaic panel according to their needs. The user can long press or short press the "Expand Photovoltaic Panel N" mode ("N" is the number of each expanded photovoltaic sheet) or "Expand Photovoltaic ALL" button in the car to send a signal (pressing the button is to turn on the expansion, and lifting the button is to turn off the expansion). The controller controls the operation of the telescopic motor of photovoltaic panel N according to the received signal to realize the extension and retraction of photovoltaic panel N, thereby increasing the illuminated area of ​​the photovoltaic panel and improving the power generation. When the user needs to exit the "expansion mode", he only needs to press the "normal mode" button in the car. The controller receives the signal to control all the telescopic motor assemblies and the lower mechanism of the lifting device. First, all the telescopic motor assemblies close the corresponding photovoltaic panels respectively, and the controller receives the retracted signal from all the telescopic motor assemblies. Then the controller controls the lower mechanism of the lifting device to close automatically. If the controller does not receive the retracted signal from all the telescopic motor assemblies, it will not send a closing signal to the lower mechanism of the lifting device, but send an alarm command to the carrier instrument to remind the user.

[0041] The photovoltaic power generation device provided in the embodiment of the present disclosure can effectively expand the area of ​​solar power generation and increase the power generation; the user can flexibly control the area of ​​solar power generation according to the usage scenario; the direction of the photovoltaic panel can be adjusted according to the location and orientation of the device to better track the movement trajectory of the sun, effectively increasing the area of ​​the photovoltaic panel directly exposed to the sun.

[0042] The present disclosure further provides a control method for a photovoltaic power generation device, including:

[0043] Obtaining location information of the photovoltaic power generation device;

[0044] The acquired position information is matched with the pre-stored position angle correspondence, and the lifting height of each lifting device is adjusted according to the matched position angle correspondence.

[0045] The stored position angle correspondence is a pre-calibrated map, which stores the angle data of the highest power generation efficiency of the photovoltaic power generation device at different longitudes and latitudes and at different times. The power generation efficiency can be reflected by the direct sunlight area. When the direct sunlight area is the largest, it can be regarded as the highest power generation efficiency.

[0046] The lifting height of each lifting device corresponds to the angle of the photovoltaic panel assembly structure. The relationship between the lifting height and the angle can also be calibrated and pre-stored in the controller, thereby achieving efficient and rapid adjustment of the angle.

[0047] The above description is only a preferred embodiment of the present disclosure and is not intended to limit the present disclosure. For those skilled in the art, the present disclosure may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present disclosure shall be included in the protection scope of the present disclosure.
